Benefit agent containing delivery particle

ABSTRACT

The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, thereby allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.

FIELD OF INVENTION

The present application relates to benefit agent containing deliveryparticles, compositions comprising such particles, and processes formaking and using such particles and compositions.

BACKGROUND OF THE INVENTION

Benefit agents, such as perfumes, silicones, waxes, flavors, vitaminsand fabric softening agents, are expensive and/or generally lesseffective when employed at high levels in consumer products, forexample, personal care compositions, cleaning compositions, and fabriccare compositions. As a result, there is a desire to maximize theeffectiveness of such benefit agents. One method of achieving suchobjective is to improve the delivery efficiencies of such benefitagents. Unfortunately, it is difficult to improve the deliveryefficiencies of benefit agents as such agents may be lost due to theagents' physical or chemical characteristics, or such agents may beincompatible with other compositional components or the situs that istreated. In an effort to improve such delivery efficiency, benefitagents have been encapsulated. Unfortunately, encapsulated benefitagents leak benefit agent over time, possibly via diffusion. Suchleakage can be minimized by increasing the encapsulate's shell strength.However, when an encapsulate's shell strength is increased, benefitssuch as sustained benefit release with time are compromised as theencapsulate no longer releases sufficient benefit agent in response tomoderate pressure stimuli. Thus, what is needed is an encapsulate thatexhibits decreased benefit agent leakage, yet which releases benefitagent in response to moderate pressure stimuli.

Here, Applicants recognized that the source of the problem giving riseto shell strength/benefit agent release dilemma was the nature ofencapsulate's crosslink density. While not being bound by theory,Applicants believe that as the shell crosslink density increases, theencapsulate's rigidity increases due to a loss of the shell's degrees offreedom and the encapsulate's benefit agent leakage decreases as thepathway through the shell is more tortuous. Thus, Applicant's recognizedthat, to exhibit low leakage and sustained release, an encapsulaterequires a high number of flexible/weak shell cross links. Such anencapsulate can, among other benefits, provide increased wet fabric odorbenefits.

Herein, Applicants provide a solution to the aforementioned dilemma.

SUMMARY OF THE INVENTION

The present invention relates to benefit agent containing deliveryparticles comprising a core material and a wall material thatencapsulates the core material. The present invention also relates tocompositions comprising said particles, and processes for making andusing such particles and compositions.

Test Methods

It is understood that the test methods that are disclosed in the TestMethods Section of the present application should be used to determinethe respective values of the parameters of Applicants' invention as suchinvention is described and claimed herein.

(1) Extraction of Benefit Agent Delivery Particles from FinishedProducts.

Except where otherwise specified herein, the preferred method to isolatebenefit agent delivery particles from finished products is based on thefact that the density of most such particles is different from that ofwater. The finished product is mixed with water in order to diluteand/or release the particles. The diluted product suspension iscentrifuged to speed up the separation of the particles. Such particlestend to float or sink in the diluted solution/dispersion of the finishedproduct. Using a pipette or spatula, the top and bottom layers of thissuspension are removed, and undergo further rounds of dilution andcentrifugation to separate and enrich the particles. The particles areobserved using an optical microscope equipped with crossed-polarizedfilters or differential interference contrast (DIC), at totalmagnifications of 100× and 400×. The microscopic observations provide aninitial indication of the presence, size, quality and aggregation of thedelivery particles.

For extraction of delivery particles from a liquid fabric enhancerfinished product conduct the following procedure:

-   -   1. Place three aliquots of approximately 20 ml of liquid fabric        enhancer into three separate 50 ml centrifuge tubes and dilute        each aliquot 1:1 with DI water (eg 20 ml fabric enhancer+20 ml        DI water), mix each aliquot well and centrifuge each aliquot for        30 minutes at approximately 10000× g.    -   2. After centrifuging per Step 1, discard the bottom water layer        (around 10 ml) in each 50 ml centrifuge tube then add 10 ml of        DI water to each 50 ml centrifuge tube.    -   3. For each aliquot, repeat the process of centrifuging,        removing the bottom water layer and then adding 10 ml of DI        water to each 50 ml centrifuge tube two additional times.    -   4. Remove the top layer with a spatula or a pipette, and    -   5. Transfer this top layer into a 1.8 ml centrifuge tube and        centrifuge for 5 minutes at approximately 20000× g.    -   6. Remove the top layer with a spatula and transfer into a new        1.8 ml centrifuge tube and add DI water until the tube is        completely filled, then centrifuge for 5 minutes at        approximately 20000× g.    -   7. Remove the bottom layer with a fine pipette and add DI water        until tube is completely filled and centrifuge for 5 minutes at        approximately 20000× g.    -   8. Repeat step 7 for an additional 5 times (6 times in total).

If both a top layer and a bottom layer of enriched particles appear inthe above described step 1, then, immediately move to step 3 (i.e., omitstep 2) and proceed steps with steps 4 through 8. Once those steps havebeen completed, also remove the bottom layer from the 50 ml centrifugetube from step 1, using a spatula or/and a pipette. Transfer the bottomlayer into a 1.8 ml centrifuge tube and centrifuge 5 min atapproximately 20000× g. Remove the bottom layer in a new tube and add DIwater until the tube is completely filled then centrifuge for 5 minutesapproximately 20000× g. Remove the top layer (water) and add DI wateragain until the tube is full. Repeat this another 5 times (6 times intotal). Recombine the particle enriched and isolated top and bottomlayers back together.

If the fabric enhancer has a white color or is difficult to distinguishthe particle enriched layers add 4 drops of dye (such as Liquitint BlueJH 5% premix from Milliken & Company, Spartanburg, S.C., USA) into thecentrifuge tube of step 1 and proceed with the isolation as described.

For extraction of delivery particles from solid finished products whichdisperse readily in water, mix 1 L of DI water with 20 g of the finishedproduct (eg. detergent foams, films, gels and granules; or water-solublepolymers; soap flakes and soap bars; and other readily water-solublematrices such as salts, sugars, clays, and starches). When extractingparticles from finished products which do not disperse readily in water,such as waxes, dryer sheets, dryer bars, and greasy materials, it may benecessary to add detergents, agitation, and/or gently heat the productand diluent in order to release the particles from the matrix. The useof organic solvents or drying out of the particles should be avoidedduring the extraction steps as these actions may damage the deliveryparticles during this phase.

For extraction of delivery particles from liquid finished products whichare not fabric softeners or fabric enhancers (eg., liquid laundrydetergents, liquid dish washing detergents, liquid hand soaps, lotions,shampoos, conditioners, and hair dyes), mix 20 ml of finished productwith 20 ml of DI water. If necessary, NaCl (eg., 100-200 g NaCl) can beadded to the diluted suspension in order to increase the density of thesolution and facilitate the particles floating to the top layer. If theproduct has a white color which makes it difficult to distinguish thelayers of particles formed during centrifugation, a water-soluble dyecan be added to the diluent to provide visual contrast. The water andproduct mixture is subjected to sequential rounds of centrifugation,involving removal of the top and bottom layers, re-suspension of thoselayers in new diluent, followed by further centrifugation, isolation andre-suspension. Each round of centrifugation occurs in tubes of 1.5 to 50ml in volume, using centrifugal forces of up to 20,000× g, for periodsof 5 to 30 minutes. At least six rounds of centrifugation are typicallyneeded to extract and clean sufficient particles for testing. Forexample, the initial round of centrifugation may be conducted in 50 mltubes spun at 10,000×g for 30 mins, followed by five more rounds ofcentrifugation where the material from the top and bottom layers isresuspended separately in fresh diluent in 1.8 ml tubes and spun at20,000×g for 5 mins per round.

If delivery particles are observed microscopically in both the top andbottom layers, then the particles from these two layers are recombinedafter the final centrifugation step, to create a single samplecontaining all the delivery particles extracted from that product. Theextracted particles should be analyzed as soon as possible but may bestored as a suspension in DI water for up to 14 days before they areanalyzed.

One skilled in the art will recognize that various other protocols maybe constructed for the extraction and isolation of delivery particlesfrom finished products, and will recognize that such methods requirevalidation via a comparison of the resulting measured values, asmeasured before and after the particles' addition to and extraction fromfinished product.

(2) Fracture Strength

To calculate the percentage of delivery particles which fall within aclaimed range of fracture strengths, three different measurements aremade and two resulting graphs are utilized. The three separatemeasurements required are namely: i) the volume-weighted particle sizedistribution (PSD); ii) the diameter of 10 individual particles withineach of 3 specified size ranges, and; iii) the rupture-force of thosesame 30 individual particles. The two graphs created are namely: a plotof the volume-weighted particle size distribution data collected at i)above; and a plot of the modeled distribution of the relationshipbetween particle diameter and fracture-strength, derived from the datacollected at ii) and iii) above. The modeled relationship plot enablesthe particles within a claimed strength range to be identified as aspecific region under the volume-weighted PSD curve, and then calculatedas a percentage of the total area under the curve.

-   -   a.) The volume-weighted particle size distribution (PSD) is        determined via single-particle optical sensing (SPOS), also        called optical particle counting (OPC), using the AccuSizer 780        AD instrument and the accompanying software CW788 version 1.82        (Particle Sizing Systems, Santa Barbara, Calif., U.S.A.). The        instrument is configured with the following conditions and        selections: Flow Rate=1 ml/sec; Lower Size Threshold=0.50 μm;        Sensor Model Number=LE400-05SE; Autodilution=On; Collection        time=120 sec; Number channels=512; Vessel fluid volume=50 ml;        Max coincidence=9200. The measurement is initiated by putting        the sensor into a cold state by flushing with water until        background counts are less than 100. A sample of delivery        particles in suspension is introduced, and its density of        particles adjusted with DI water as necessary via autodilution        to result in particle counts of at least 9200 per ml. During a        time period of 120 seconds the suspension is analyzed. The        resulting volume-weighted PSD data are plotted and recorded, and        the values of the mean, 5^(th) percentile, and 90^(th)        percentile are determined.    -   b.) The diameter and the rupture-force value (also known as the        bursting-force value) of individual particles are measured via a        computer-controlled micromanipulation instrument system which        possesses lenses and cameras able to image the delivery        particles, and which possess a fine, flat-ended probe connected        to a force-transducer (such as the Model 403A available from        Aurora Scientific Inc, Canada), as described in: Zhang, Z. et        al. (1999) “Mechanical strength of single microcapsules        determined by a novel micromanipulation technique.” J.        Microencapsulation, vol 16, no. 1, pages 117-124, and in:        Sun, G. and Zhang, Z. (2001) “Mechanical Properties of        Melamine-Formaldehyde microcapsules.” J. Microencapsulation, vol        18, no. 5, pages 593-602, and as available at the University of        Birmingham, Edgbaston, Birmingham, UK.    -   c.) A drop of the delivery particle suspension is placed onto a        glass microscope slide, and dried under ambient conditions for        several minutes to remove the water and achieve a sparse, single        layer of solitary particles on the dry slide. Adjust the        concentration of particles in the suspension as needed to        achieve a suitable particle density on the slide. More than one        slide preparation may be needed.    -   d.) The slide is then placed on a sample-holding stage of the        micromanipulation instrument. Thirty benefit delivery particles        on the slide(s) are selected for measurement, such that there        are ten particles selected within each of three pre-determined        size bands. Each size band refers to the diameter of the        particles as derived from the Accusizer-generated        volume-weighted PSD. The three size bands of particles are: the        Mean Diameter+/−2 μm; the 5^(th) Percentile Diameter+/−2 μm; and        the 90^(th) Percentile Diameter+/−2 μm. Particles which appear        deflated, leaking or damaged are excluded from the selection        process and are not measured.    -   e.) For each of the 30 selected particles, the diameter of the        particle is measured from the image on the micromanipulator and        recorded. That same particle is then compressed between two flat        surfaces, namely the flat-ended force probe and the glass        microscope slide, at a speed of 2 μm per second, until the        particle is ruptured. During the compression step, the probe        force is continuously measured and recorded by the data        acquisition system of the micromanipulation instrument.    -   f.) The cross-sectional area is calculated for each of the        selected particles, using the diameter measured and assuming a        spherical particle (πr², where r is the radius of the particle        before compression). The rupture force is determined for each        selected particle from the recorded force probe measurements, as        demonstrated in Zhang, Z. et al. (1999) “Mechanical strength of        single microcapsules determined by a novel micromanipulation        technique.” J. Microencapsulation, vol 16, no. 1, pages 117-124,        and in: Sun, G. and Zhang, Z. (2001) “Mechanical Properties of        Melamine-Formaldehyde microcapsules.” J. Microencapsulation, vol        18, no. 5, pages 593-602.    -   g.) The Fracture Strength of each of the 30 particles is        calculated by dividing the rupture force (in Newtons) by the        calculated cross-sectional area of the respective particle.    -   h.) On a plot of particle diameter versus fracture-strength, a        Power Regression trend-line is fit against all 30 raw data        points, to create a modeled distribution of the relationship        between particle diameter and fracture-strength.    -   i.) The percentage of particles which have a fracture strength        value within a specific strength range is determined by viewing        the modeled relationship plot to locate where the curve        intersects the relevant fracture-strength limits, then reading        off the particle size limits corresponding with those strength        limits. These particle size limits are then located on the        volume-weighted PSD plot and thus identify an area under the PSD        curve which corresponds to the portion of particles falling        within the specified strength range.    -   j.) The identified area under the PSD curve is then calculated        as a percentage of the total area under the PSD curve. This        percentage indicates the percentage of delivery particles        falling with the specified range of fracture strengths.

(3) Clod′

The log P values of many perfume ingredients have been reported; forexample, the Pomona92 database, available from Daylight ChemicalInformation Systems, Inc. (Daylight CIS, Irvine, Calif.), contains many,along with citations to the original literature. However, the log Pvalues are most conveniently calculated by the “CLOGP” program, alsoavailable from Daylight CIS. This program also lists experimental log Pvalues when they are available in the Pomona92 database. The “calculatedlog P” (C log P) is determined by the fragment approach of Hansch andLeo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C.Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295,Pergamon Press, 1990, incorporated herein by reference). The fragmentapproach is based on the chemical structure of each perfume ingredient,and takes into account the numbers and types of atoms, the atomconnectivity, and chemical bonding. The C log P values, which are themost reliable and widely used estimates for this physicochemicalproperty, are preferably used instead of the experimental log P valuesin the selection of perfume ingredients which are useful in the presentinvention.

(4) Boiling Point

The boiling point of perfume ingredients is measured according tostandard test method ASTM D2887-04a, “Standard Test Method for BoilingRange Distribution of Petroleum Fractions by Gas Chromatography,” (ASTMInternational, West Conshohocken, Pa., USA. Section 5.2 of that methodnotes: “Boiling range distributions obtained by this test method areessentially equivalent to those obtained by true boiling point (TBP)distillation (see Test Method D 2892). They are not equivalent toresults from low efficiency distillations such as those obtained withTest Method D 86 or D 1160.”

(5) Particle Size (Diameter):

A drop of the particle suspension or finished product is placed onto aglass microscope slide and dried under ambient conditions for severalminutes to remove the water and achieve a sparse, single layer ofsolitary particles on the dry slide. Adjust the concentration ofparticles in the suspension as needed to achieve a suitable particledensity on the slide. The slide is placed on a sample stage of anoptical microscope equipped and examined at a total magnification of100× or 400×. Images are captured and calibrated for the accuratemeasurement of particle diameters. Three replicate slides are preparedand analyzed.

For particle size measurement, at least 50 benefit agent deliveryparticles on each slide are selected for measurement, in a manner whichis unbiased by their size and so creates a representative sample of thedistribution of particle sizes present. This may be achieved byexamining fields-of-view which are selected at random or according to apre-defined grid pattern, and by measuring the diameter of all thedelivery particles present in each field-of-view examined. Deliveryparticles which appear obviously non-spherical, deflated, leaking, ordamaged are unsuitable for measurement, are excluded from the selectionprocess and their diameters are not recorded. The diameter of eachsuitable delivery particle examined is measured using the microscope andthe value is recorded. The recorded particle diameter measurements areused to calculate the percentage of the particles having a particle sizewithin the claimed size range(s), and also to calculate the meanparticle size.

(6) Particle Wall Thickness

The particle wall thickness is measured in nanometers on 50 benefitagent delivery particles using freeze-fracture cryo-scanning electronmicroscopy (FF cryoSEM), at magnifications of between 50,000× and150,000×. Samples are prepared by flash freezing small volumes of asuspension of particles or finished product. Flash freezing can beachieved by plunging into liquid ethane, or through the use of a devicesuch as a High Pressure Freezer Model 706802 EM Pact, (LeicaMicrosystems, Wetzlar, Germany). Frozen samples are fractured while at−120° C., then cooled to below −160° C. and lightly sputter-coated withgold/palladium. These steps can be achieved using cryo preparationdevices such as those from Gatan Inc., (Pleasanton, Calif., USA). Thefrozen, fractured and coated sample is then transferred at −170° C. orlower, to a suitable cryoSEM microscope, such as the Hitachi S-5200SEM/STEM (Hitachi High Technologies, Tokyo, Japan). In the HitachiS-5200, imaging is performed with 3.0 KV accelerating voltage and 5μA—20 μA tip emission current.

Images are acquired of the fractured wall in cross-sectional view from50 benefit delivery particles selected in a random manner which isunbiased by their size, so as to create a representative sample of thedistribution of particle sizes present. The wall thickness of each ofthe 50 particles is measured using the calibrated microscope software,by drawing a measurement line perpendicular to the outer surface of theparticle wall. The 50 independent wall thickness measurements arerecorded and used to calculate the mean thickness, and the percentage ofthe particles having a wall thickness within the claimed range.

(7) Benefit Agent Leakage

The amount of benefit agent leakage from the delivery particles isdetermined according to the following method:

-   -   a.) Obtain two 1 g samples of the raw material slurry of benefit        delivery particles.    -   b.) Add 1 g of the raw material slurry of benefit delivery        particles to 99 g of the product matrix in which the particles        will be employed, and label the mixture as Sample 1. Immediately        use the second 1 g sample of raw material particle slurry in        Step d below, in its neat form without contacting product        matrix, and label it as Sample 2.    -   c.) Age the particle-containing product matrix (Sample 1) for 2        weeks at 35° C. in a sealed, glass jar.    -   d.) Using filtration, recover the particles from both samples.        The particles in Sample 1 (in product matrix) are recovered        after the aging step. The particles in Sample 2 (neat raw        material slurry) are recovered at the same time that the aging        step began for sample 1.    -   e.) Treat the recovered particles with a solvent to extract the        benefit agent materials from the particles.    -   f.) Analyze the solvent containing the extracted benefit agent        from each sample, via chromatography. Integrate the resultant        benefit agent peak areas under the curve, and sum these areas to        determine the total quantity of benefit agent extracted from        each sample.    -   g.) Determine the percentage of benefit agent leakage by        calculating the difference in the values obtained for the total        quantity of benefit agent extracted from Sample 2 minus Sample        1, expressed as a percentage of the total quantity of benefit        agent extracted from Sample 2, as represented in the equation        below:

${{Percentage}\mspace{14mu} {of}\mspace{14mu} {Benefit}\mspace{14mu} {Agent}\mspace{14mu} {Leakage}} = {( \frac{{{Sample}\mspace{14mu} 2} - {{Sample}\mspace{14mu} 1}}{{Sample}\mspace{14mu} 2} ) \times 100}$

(8) Viscosity

Viscosity of liquid finished product is measured using an AR 550rheometer/viscometer from TA instruments (New Castle, Del., USA), usingparallel steel plates of 40 mm diameter and a gap size of 500 μm. Thehigh shear viscosity at 20 s⁻¹ and low shear viscosity at 0.05 s⁻¹ isobtained from a logarithmic shear rate sweep from 0.1 s⁻¹ to 25 s⁻¹ in 3minutes time at 21° C.

(9) Free Formaldehyde

Free formaldehyde in finished product is measured in accordance with thestandard method NIOSH 5700 Formaldehyde on Dust (NIOSH Manual ofAnalytical Methods, Fourth Edition, August 1994, The National Institutefor Occupational Safety and Health, Centers for Disease Control andPrevention, Atlanta, Ga., USA), with the following adaptations:

-   -   Adaptation of DNPH concentration: minimize polymer degradation        during derivatization reaction and create condition to monitor        fate of derivatization reagent during subsequent LC analysis        (check for potential reagent consumption by other sample        constituents such as perfume carbonyls).    -   Reduction of the acid concentration and use of hydrochloric acid        instead of perchloric acid: create milder conditions for        derivatization, avoiding excessive polymer/resin degradation.        (Derivatization kinetics at these conditions are checked to show        reaction plateau is reached at about 10 min)    -   Solvent extraction (Acetonitrile): ensures fast separation of        the solid material from samples and allowing for easy        filtration. The filtrate contains formaldehyde for analysis.        Standard calibration solutions are made up to match the solvent        composition to that of samples analyzed to ensure equal reaction        conditions for derivatization.

Add very        slowly, while stirring vigorously, 700 mL of acetonitrile.        Filter through a 0.45 μm disposable filter cup. It is very        important to mix well and add the acetonitrile very slowly to        prevent the precipitation of the Pic A as much as possible.        Preferably, prepare this eluent well in advance to allow        equilibration and avoid precipitation during use. Filter before        use.    -   (3) 2,4 Dinitrophenylhydrazine stock solution. Weigh, to the        nearest 0.01 g, 0.4 g of 2,4-DNPH in a 100 mL glass bottle. Add        20 ml of ethanol absolute and stir vigorously.

Pipette 5 mL of the 2,4-dinitrophenylhydrazine stock solution        into a 100 mL glass volumetric flask. Fill to volume with de        ionized water and mix well. The 2,4-DNPH working solution has to        be re-made daily.    -   (5) 2,4 Dinitrophenylhydrazine working solution for standards.        Pipette 5 mL of the 2,4-dinitrophenylhydrazine stock solution        into a 100 mL glass volumetric flask. Fill to volume with        acetonitrile mix well. The 2,4-DNPH working solution has to be        re-made daily.

Procedure

-   -   1) Formaldehyde standard stock solution: Weigh, to the nearest        0.0001 gram, 1.0 g of formaldehyde standard into a small sample        cup. Dissolve into a 1 L volumetric flask using deionized water.        Record the weight as Wst    -   2) Preparation of standard working solutions        -   a. Pipette 5 mL of the formaldehyde stock solution into a 50            mL volumetric flask. Bring to volume with de ionized water            and mix well.        -   b. Pipette 0, 0.5, 1.0, 3, and 5 mL of the diluted stock            solution into separate 50 mL volumetric flasks. Bring to            volume with de ionized water and mix well. Filter            approximately 5 mL of each standard working solution through            a 0.45 μm disposable filter unit into a glass vial.    -   3) Sample preparation: Weigh, to the nearest 0.0001 gram, about        1 gram of sample into a 50 mL volumetric flask. Bring to volume        with acetonitrile and mix well. Allow about five (5) minutes for        the insoluble material to settle. Filter approximately 5 mL of        the sample solution through a 0.45 μm disposable filter unit        into a glass vial. Record the exact weight as Wsa in grams.    -   4) Derivatization procedure        -   a. Pipette 1.00 mL of each standard solution, filtered            sample solution, and filtered extract into separate 4 mL            sample vials. The choice of the calibration range is            dependent on the expected free formaldehyde level in sample            solutions or extracts.        -   b. Standards: add 1.00 mL of 2,4-DNPH working solution for            standards to each vial. Stopper and mix.        -   c. Samples: add 1.00 mL of 2,4-DNPH working solution for            samples to each vial. Stopper and mix.        -   d. Let react for 10 minutes±20 seconds before injection.            Note: this timing is critical. Start the timer as soon as            the reagents are mixed and take into account the time it            takes to load and inject a sample.    -   5) Instrumental Operation: Set up the HPLC system according to        the manufacturer's instructions using the following conditions:        -   Isocratic: 20% A—80% B/0.8 ml/min        -   Detection: UV at 365 nm        -   Inj. volume: 20 μl        -   Runtime: 10 minutes

Calibration

-   -   1) Inject 20 μl of a derivatized standard solution at least once        to check for proper instrument functioning (Never use the area        counts of the first injection for calibration purposes. The        first injection after start up of the HPLC system is generally        not representative).    -   2) Inject 20 μl of each of the derivatized standard solutions.    -   3) Record the peak areas and, with the help of the examples in        appendix 9, assign the peak identity.

Analysis of the samples

-   -   1) Inject 20 μl of each of the derivatized sample solutions or        extracts.    -   2) Record the peak area for the formaldehyde peak.    -   3) After analyses are finished, replace the eluent by de ionized        water and then a storage solvent, e.g. HPLC grade methanol,        before removing the column from the system.

Calculations

(1) Calculate the amount of formaldehyde in each of the standardsolutions (calibration range: 0-5 μg/mL)

${\underset{\_}{vol}\mspace{14mu} {\mu g}\mspace{14mu} {formaldehyde}\text{/}{mL}} = {\frac{{Wst} \times {Ast} \times 1000 \times {Dil}\mspace{14mu} {vol}}{100 \times 10 \times 50} = \frac{{Wst} \times {Ast} \times {Dil}}{50}}$

Where:

-   -   Wst=weight of standard in the stock solution in grams (7.1.1)    -   Ast=Activity of the standard material (%) determined by        titration (7.1.5)    -   Dil vol=diluted standard stock amounts in mL used for preparing        standard solutions (0-10 mL)        (2) Construct a calibration curve (amounts versus peak area).        When using the Waters Millennium 2010 data processing software,        perform the ‘Fit Type’: Linear calibration setting in ‘Component        table’ of the Processing Method.        (3) Starting from the formaldehyde peak area of a sample, read        the amount of formaldehyde in the sample solution or extract in        μg/mL from the calibration curve. Record this value as μg_(sa):        Note: this calculation assumes that injection volumes of        standards and samples are identical.        (4) Calculate the amount of formaldehyde in the samples as        follows:

${{ppm}\mspace{14mu} {formaldehyde}} = \frac{\mu \; {gsa} \times 100}{Wsa}$

Where:

-   -   μgsa=amount of free formaldehyde in the sample solution in μg/mL        (7.3)    -   Wsa=weight of sample in grams (7.3.1)

(10) Perfume and Perfume Raw Materials (PRMs)

To determine the identity and to quantify the weight of perfume, perfumeingredients, or Perfume Raw Materials (PRMs), encapsulated within thedelivery agent particles, Gas Chromatography with MassSpectroscopy/Flame Ionization Detector (GC-MS/FID) is employed. Suitableequipment includes: Agilent Technologies G1530A GC/FID; Hewlett PackerMass Selective Device 5973; and 5%-methylpolysiloxane Column J&W DB-5(30 m length×0.25 mm internal diameter×0.25 μm film thickness).Approximately 3 g of the finished product or suspension of deliveryparticles, is weighed and the weight recorded, then the sample isdiluted with 30 mL of DI water and filtered through a 5.0 μm pore sizenitrocellulose filter membrane. Material captured on the filter issolubilized in 5 mL of ISTD solution (25.0 mg/L tetradecane in anhydrousalcohol), and heated at 60° C. for 30 minutes. The cooled solution isfiltered through 0.45 μm pore size PTFE syringe filter and analyzed viaGC-MS/FID. Three known perfume oils are used as comparison referencestandards. Data Analysis involves summing the total area counts minusthe ISTD area counts, and calculating an average Response Factor (RF)for the 3 standard perfumes.

(12) Method for Analysis of Styrene Maleic Anhydride Monomethylmaleate,and or/a Salt Thereof (SMAM) in Benefit Agent Delivery Particles

The objective of the method described herein is to identify anddetermine the amount of Styrene Maleic Anhydride Monomethylmaleate(SMAM) in delivery particles comprising aminoplast, polyacrylate and/orpolymethacrylate wall chemistries. This method assumes that the speciesof Styrene Maleic Anhydride used in the delivery particle is StyreneMaleic Anhydride Monomethylmaleate, and or/a salt thereof and not amixture of SMAM with other styrene maleic anhydrides. The benefit agentdelivery particles are also referred to as “delivery particle” and/or“delivery particles” in this method. The method consists of extractingdelivery particle walls from finished products by filtration, extractingthe delivery particle wall materials, and quantifying the amount of SMAusing ATR-FTIR Spectroscopy.

-   -   1. All solvents used are of HPLC reagent grade, and water is        filter-sterilized, deionized water. Weigh approximately 2 grams        of the sample to be tested into an appropriately sized tri-pour        beaker. Dilute with 5 mL DI water and mix well. Add 20 mL of        isopropyl alcohol (IPA). Add 20 mL of hexane and mix briefly.        Use a 60 mL syringe housing to filter the sample through a        polycarbonate, hydrophilic screen filter having a 1.2 μm pore        size and 25 mm diameter (Millipore Isopore Membrane), via a        filter mounting assembly (eg. Swinnex) attached to a vacuum        manifold. Rinse the filter several times with hexane and/or IPA.    -   2. Repeat step 1 at least ten times to isolate enough delivery        particles.    -   3. Carefully remove the filters and transfer all of them into a        50 mL centrifuge tube.    -   4. Add 5-15 mL of methanol, IPA, hexane or a mixture thereof to        the tube. The tube may also be heated for 30 minutes at 60° C.        to help remove perfumes.    -   5. Place the tube in an ultrasonic cleaning bath for at least 5        minutes, preferably longer, to remove the particles from the        filter. Remove the filters from the tube with tweezers.    -   6. Centrifuge the tube for at least 5 minutes at a minimum of        5000 rpm. If multiple layers are formed, confirm the presence of        delivery particles via light microscopy by sampling a small        amount from each layer. Separate the layer(s) containing        delivery particles from the solution via decantation or with a        transfer pipette.    -   7. Suspend the fraction containing delivery particles in DI        water, shake the tube and centrifuge again. Separate the        solution from the solids via decantation or with a transfer        pipette. Add a few mL of DI water to the solids, shake and        freeze using liquid nitrogen. Freeze-dry the sample until        complete dryness is achieved (at least 24 hours).    -   8. Using a Perkin Elmer Spectrum Two FTIR spectrometer equipped        with DTGS detector and Perkin Elmer diamond ATR accessory        (Perkin-Elmer, Waltham Mass., USA), collect an ATR-FTIR spectrum        of a small amount of the extracted delivery particle wall        material. Identify the wall chemistry as melamine or        polyacrylate by comparing with a melamine standard and a        polyacrylate standard, FTIR library search or literature        reference. FTIR spectra are collected using at least 8 co-added        scans at a resolution of 4 cm⁻¹. Melamine chemistry is        identified by the characteristic melamine peak at 815-810 cm⁻¹,        together with peaks at approximately 1550 cm⁻¹, 1490 cm⁻¹, 1340        cm⁻¹, 1160 cm⁻¹ and 1017 cm⁻¹. Polyacrylate chemistry is        identified by the characteristic acrylate carbonyl peak at        1735-1725 cm⁻¹, together with peaks at approximately 1456 cm⁻¹,        1407 cm⁻¹, 1160 cm⁻¹, 1061 cm⁻¹, 809 cm⁻¹ and 759 cm⁻¹.    -   9. Add 10-15 mL of methanol, hexane or IPA to the centrifuge        tube that contains the freeze-dried particle wall material from        step 7. Shake and sonicate for at least 10 minutes. Centrifuge        for at least 5 minutes at a minimum of 5000 rpm. Decant the        solvent. Repeat this step at least twice.    -   10. Repeat step 7.    -   11. Collect an ATR-FTIR spectrum of the extracted particle wall        material. Compare the 720-690 cm⁻¹ IR region with the same        region of the IR spectrum collected in step 8 if wall is        melamine or compare with the 1800-650 cm⁻¹ region if wall is        polyacrylate        -   11.1 If no differences are observed and the SMAM peak at            700±3 cm⁻¹ is still observed then proceed to steps 12-20 for            the SMAM analysis in melamine delivery particles, or to            steps 21-29 for the SMAM analysis in polyacrylate delivery            particles.        -   11.2 For melamine particles, if changes occurred in this            region, for instance, a peak at 700±3 cm⁻¹ was observed in            step 8 and its intensity decreased in step 11, then repeat            steps 9 to 11 until no changes in the 720-690 cm⁻¹ IR region            are observed. If the peak at 700±3 cm⁻¹ ultimately            disappears while the melamine peak at 815-810 cm⁻¹ remains            present, then no SMAM quantification is needed.        -   11.3 For polyacrylate wall particles, if changes occurred in            this region, for instance, a peak at 700±3 cm⁻¹ was observed            in step 8 and its intensity decreased in step 11, then            repeat steps 9 to 11 until no changes in the 1800-650 cm⁻¹            IR region are observed. If the peak at 700±3 cm⁻¹ ultimately            disappears while the polyacrylate peak at 1735-1725 cm⁻¹            remains present, then no SMAM quantification is needed.

(13) Method for Analysis of Styrene Maleic Anhydride Monomethylmaleate,and or/a Salt Thereof (SMAM) Hydrolysis Degree

For purpose of this application, Hydrolysis Degree is the determined. asfollows:

The raw material SMA polymer is analyzed via Fourier-TransformedInfra-Red Spectroscopy (FTIR), after removing all liquid viafreeze-drying. Approximately 50 mg of the freeze-dried material may thenbe re-dissolved in 2 mL methanol in order to cast a thin film usingapproximately 200 μL of the solution cast over a polyethylene sample IRcard. The solution is allowed to air dry for 30 minutes prior to FTIRanalysis. The anhydride and the acid (hydrolyzed) unit are eachquantified from the peak absorbance present at their respectivecharacteristic absorption bands in the FTIR spectra, namely: 1770-1790cm⁻¹ for anhydride, and 1700-1720 cm⁻¹ for COOH acid (hydrolyzedpolymer). The IR spectrum (from 4000 cm⁻¹ to 500 cm⁻¹ at a resolution of4 cm⁻¹) is recorded using a plain uncoated polyethylene sample IR cardas the background.

The percent hydrolysis of the polymer is determined by calculating theratio of the peak absorbances of the acid units, to the sum of the acidunits and anhydride units, and via the following equation:

Percent Hydrolysis=(maleic acid/(maleic acid+maleic anhydride))×1.00

Wherein the terms “maleic acid” and “maleic anhydride” represent thepeak absorbance of each polymer unit respectively, as determined byquantitative Fourier-Transformed Infra-Red. Spectroscopy (FTIR) usingthe characteristic absorption bands of: 1770-1790 cm⁻¹ for anhydride and1700-1720 cm⁻¹ for COOH acid (hydrolyzed).
